Well, my empeg is having IDE problems again. The age old
Probing primary interface...

empeg-flash driver initialized

(not finding the drive) issue. I had a similar problem about a year ago, resolderd the IDE head, was still flaky while I had it out of the case, put it back together and it just magically worked. See previous thread of mine. It has been working since. Until last night, the night before I was supposed to drive to phoenix, of course. I was mucking around with it last night for a while, without avail. Re-soldered the IDE header again, no love. Then I saw something weird. You'll notice that two of the pins on the cs4231a chip are bridged. This looks like it was a factory thing, because there's no way I could've done that neat of a job on a screw up. So I don't know if this is contributing to my problem or not, because things have apparently been working with it. But the thing I don't know is if this chip is also the IDE controller?

Full boot log, you'll see that the chip is being initialized properly.

Here are all of the pictures I've taken of various things, including the IDE header.

I'm hesitant to try and undo the solder bridge on the cs4231a chip, I may screw it up unnecesarilly, so if anyone has thoughts on that..

In the mean time, I'll re-solder the IDE header again, I really do not want to go on a 12 hour road trip without music

As I remember, that bridge is intentional.

Will do, I'll leave that alone. But I did go over the IDE header several times to no avail. Even went so far as to push them to make sure that the pads were in fact making contact with the surface. However, in this process of pushing them, many of them did move, so I had to bend the leads back so that I could attach the cable, but this seemed to keep pulling the pads back, because I'd go over it again with the soldering iron, and they'd move some more. I kept screwing with it, tried to put the cable back on, and one of the leads was a bit too far out, so pushing the cable on, this one lead was bent all the way over. I pushed it back, and it snapped. Someone up there does not want me to go on this road trip. I added a couple more photos of my hack job just to get the bloody thing working.

Still in progress..

Any other thoughts other than the IDE header?

Bad cable.

I should've put more info in the original post, I apologize.

I did purchase a spare IDE cable, and swapping that out as well as re-pressing the crimp as well as swapping the drives out, same result.

My horrible hack for the snapped pin isn't working either. I just went to Fry's to see if they had something I could use to replace the whole IDE head, but as I'm sure most everyone knows, something like that just doesn't seem to be readily available.

I wonder how much a 40g iPod costs :/

Hang on, you've broken a pin off the main board IDE header? I thought you'd broken a connector from the way you described it. Which pin is broken?

You are not going to get a replacement header rail from Frys. I have spares here, but you'd have to send me the board.

Just looked at your pictures again: you're in trouble. The broken pin is a data line.
